Promises, promises, Promises,,, They have a great idea and the potential for a new powerplant is right on thier doorstep. They just can't seem to figure out how to open that door. After hearing, "next month" for years now my bets are they will deliver engines to customers in 2012, Maybe......................... do not archive Ben Haas N801BH www.haaspowerair.com I offer an opinion on Deltahawk. For several years the company proceeded methodically and steadily with development of their engine. They kept close to their stated timetables for the most part. At one point they spoke of contracting the mfg. of parts and doing the assembly themselves. Later, the entire manufacturing and assembly was dealt off to an outside outfit, not experienced in engine building. The transition has taken more time than anticipated. Until recent months no showstoppers had been encountered. Then a glitch appeared which may not be a showstopper but has slowed progress. The Hartzell propeller/Deltahawk combination presented torsional vibrations that needed attention. It is not clear that to date these have been resolved. Workarounds such as wood, composites, etc. are being evaluated and I'm not aware of results having been published. I recently spoke with a gentleman who knows some things about diesels and he described some on the limitations of the mechanical injection system chosen by Deltahawk. We'll have to await the outcome. Dh intended to contract fwf development to others and perhaps that work is underway. Installation of such an engine in an aircraft not designed for it is not for the faint of heart and is outside my skill/timeframe abilities, so I cancelled the order I had placed and turned to the Lyc 390 package. For those who can wait and have the energy to tackle such a project, I think optimism is still justified but if one doesn't have the luxury of time, I'd suggest looking elsewhere. The prospect of sealevel power at higher altitudes is very appealing, but, and it's a big "but", the flutter resistance of Van's designs have been called into question. Ken Krueger is dogmatic on the subject. He flat says, "don't do it." I personally don't know but would look forward to an independent analysis. If it is a problem, then the question becomes, "what can be done about it, if anything." I hope I have not mischaracterized Deltahawk. There may be things I'm not aware of. It is not my intent to belittle them, on the contrary, they have done an outstanding job of identifying and coping with the problems inherent in such a development project and I wish them well. I certainly hope they do not go the way of Zoche's Aerodiesel.
